  1. The following example consist of a single meta surface that is used to define the bow of a large varieties of ship kinds. The model permit large variations of the shape from a typical bulbous bow of large vessels to vertical bows as seen in sailing boats, for instance. First a station is defined by points as the keel, bilge, waterline and deck, plus some auxiliary points used to control the tangent of each curve, as to say to guarantee a smooth transaction between each section of the station. Then those points "runs" along the X-axis varying the coordinates, defining the station at each "X" position of the station. The points and curves of each station are the same, however transformed as defined by some "curve functions", in function of X-position. Thus, the same curve I used to define the bilge at the aft zone I also use to define the bulb at the fore end of the bow. This simple model shows the geniality, by simplicity, of a parametric model defined via meta surfaces. In this model the variables are: -Beam -Length -Depth -Draft -Entrance Angle -Stem Angle -Bilge Radius -Bulb Beam -Bulb Height Finally, TPOs is used to see the station variation along the X-axis.
